Background technology
Known guideway vehicle, it has measurement mechanism at different vehicle part places, to detect the observed reading of measurand.Like this, such as, on the traction motor of guideway vehicle, be provided with temperature-sensitive sticker, to record the observed reading of the temperature of traction motor.Subsequently, the mode by observed reading such as being compared with the threshold value determined before respectively assesses the observed reading on the car of guideway vehicle.If the observed reading of vehicle part exceedes threshold value, so show the fault of vehicle part.The assessment result of observed reading also can send the control center of side, land setting to and export at that.
Summary of the invention
The object that the present invention is based on is, proposes a kind of method and a kind of system, makes accurately predicting just to safeguard.
Described object is realized by the theme of independent claims 1 and 9.Improvement project of the present invention and design plan are reflected in the feature of dependent claims.
According to of the present invention for diagnosing the method for one or more guideway vehicle, described guideway vehicle comprises at least one measurement mechanism of the observed reading for detecting at least one measurand respectively, and described method comprises the steps:
-observed reading of at least one measurand is detected by means of at least one measurement mechanism of guideway vehicle;
-observed reading is transferred to the control center being arranged on line side from guideway vehicle;
-in the controlling in the heart by means of the algorithm evaluation observed reading preset; And
-provide at least one result of assessment for being exported by control center.
At least one guideway vehicle of at least one guideway vehicle, especially passenger traffic comprises at least one measurement mechanism, sometimes also referred to as survey record device.Described measurement mechanism to be especially arranged in guideway vehicle or to move together on guideway vehicle and along with guideway vehicle.As the list of the exhaustive of measurement mechanism, enumerate at this: speed gauge, potential device, humidity sensor, inclination sensor, current/voltage detecting device, temperature-sensitive sticker and/or position sensing device.
The transmission of observed reading from guideway vehicle to control center is such as wirelessly carried out.At this, wireless transmission at least piecewise realizes, and namely transmission need not be all wireless on the whole path from guideway vehicle to control center.Wireless transmission is such as connected by DF ü, is such as carried out between guideway vehicle and the transmitting and receiving device of described network via GSM network, UMTS network or LTE network.Between reception facilities and control center, the further transmission of observed reading also can be carried out in a wired fashion.Observed reading is transferred to control center from guideway vehicle with improved procedure in the cycle of presetting.At this, the transmission of observed reading from guideway vehicle to control center especially not by guideway vehicle vehicle part preset state or state variation carry out with affecting.Control center is in line side and and then in side, land and especially position is regularly and arrange away from guideway vehicle.
There, observed reading is assessed by means of the algorithm preset.For this reason, control center especially has controller, and described controller is suitable for by means of the algorithm preset to assess observed reading.Algorithm advantageously exists as software.This results in the simple and advantage of fast adaptation algorithm.The intermediate result of algorithm and observed reading and assessment also can be preserved in memory.Assessment obtains at least one result.At least one result described is provided by control center.
Described result to be transferred on guideway vehicle and to export with the form preset there, such as visual, and/or the result of assessment exports with the form preset in the heart in line side, especially in the controlling, such as visual.As an alternative, the output in customers' place is also possible.The result of assessment also can provide via internet, to utilize described result from different positions.Visually such as to carry out as the display on screen.Except visual, acoustics output, tactile feedback or SMS are considered as other output forms.Multiple corresponding form can be had equally to the result that observed reading is assessed by means of the algorithm preset.This can be simple danger signal, and described danger signal exports to the vehicle driver of guideway vehicle as acoustic alert.On the other hand, also can relate to the diagnosis at least one vehicle part of guideway vehicle or failure prediction, it exports to maintenance team for the maintenance plan setting up guideway vehicle.In addition, life forecast will be mentioned as other examples at this.The method is suitable for predictive maintenance, English predictive maitenance, and and then is suitable for carrying out predicting and/or in order to prevent this, planning corresponding service intervals about the possibility of the technical failure of vehicle part.
In order to result is transferred to guideway vehicle from control center, control center and guideway vehicle have transmitting apparatus complimentary to one another and reception facilities.Then, the described result control center that especially piecewise is wirelessly arranged from line side is transferred to guideway vehicle.
Except having the possibility of unrestricted accessing result on place, result is provided also to have other advantages of time upper unrestricted accessing by control center.Like this, according to another embodiment, in the time period of presetting, multiple results of different time points to be stored in control center and to be provided for exporting.On the one hand, memory device need not move together in guideway vehicle.On the other hand, the output of one or more result also according to event and the result itself according to assessment, or can be carried out according to the state of guideway vehicle or at least one or more vehicle part of state variation or guideway vehicle.This is called by event control.
If the object of assessment is such as the operating characteristic of the instant safety determining guideway vehicle, the result so assessed can be described as " affirmative " or " negative ".Described result itself is provided by control center, is namely " affirmative ".But " affirmative " result is not transmitted and/or exports, " negative " result is only had to be transmitted and/or to export, such as, as " danger signal " to vehicle driver.The output of at least one result from control center to guideway vehicle and/or transmission can depend on the output of assessment thus.And the transmission of observed reading from guideway vehicle to control center not by guideway vehicle vehicle part preset state or state variation carry out with affecting.Also namely, do not relate to the transmission by event control at this, but described transmission is performed periodically.
Reason according to another advantage of method of the present invention is, other observed readings can be assessed by means of the algorithm preset, and described observed reading detects by means of the measurement mechanism do not affected by guideway vehicle.The measurement mechanism do not affected by described guideway vehicle and guideway vehicle have nothing to do.Therefore, by described measurement mechanism and guideway vehicle or the state of vehicle part of guideway vehicle or state variation independently detect other observed readings.Other observed readings described are the observed readings about at least one measurand, also detect the observed reading of guideway vehicle about described measurand, and/or other observed readings are the observed readings about other measurands.The measurement mechanism do not affected by guideway vehicle does not move together with guideway vehicle.But, and not necessarily must be fixing measurement mechanism, such as described measurement mechanism is also arranged on another vehicle, especially guideway vehicle, such as, on the guideway vehicle that structure is identical.But especially, measurement mechanism is the measurement mechanism being arranged on line side, can not moving.By assessing by means of identical algorithm, do not affect by guideway vehicle, independently other observed readings of measurement mechanism include in together in the assessment result of the observed reading of the measurement mechanism of guideway vehicle.
At this, that do not affect by guideway vehicle, that independently other observed readings of measurement mechanism especially detect with the measurement mechanism by guideway vehicle observed reading has nothing to do.Contrary situation might not be suitable for.Like this, such as temperature-sensitive sticker detects the measurand of vehicle part such as traction motor of guideway vehicle and the observed reading of temperature as the measurement mechanism of guideway vehicle.Not by guideway vehicle affect and independently temperature sensing such as along the line location of guideway vehicle, with regard to it detect travel process guideway vehicle surrounding environment in air themperature.Like this, the temperature by the rising of the air of surrounding environment affects, and the temperature of traction motor raises.And the temperature of the rising of traction motor on the temperature of the air of surrounding environment only have inapparent impact and and then can ignore (in illustrative example the temperature of the air of surrounding environment be considered as with the temperature of the traction motor of guideway vehicle have nothing to do.
By other observed readings detected to the measurement mechanism that guideway vehicle has nothing to do such as by middle position as Meteorological Services station detect and with guideway vehicle directly or indirectly surrounding environment is relevant.At this, the direct surrounding environment of guideway vehicle such as comprises environment or the Infrastructure such as line characteristic of guideway vehicle.Also can consider with vehicle independently (fahrzeugfrei) and relevant but not by the observed reading that the vehicle part of same configuration detects with affecting with vehicle.Especially, described method by assessment in the heart in the controlling therefore, it is possible to realize considering not relevant to vehicle observed reading.
According to another improvement project of method according to the present invention, when considering other observed readings detected by means of the measurement mechanism had nothing to do with guideway vehicle, in the controlling in the heart by means of the observed reading that default algorithm evaluation detects by means of at least one measurement mechanism of at least one guideway vehicle.
Except the observed reading detected by means of at least one measurement mechanism of at least one guideway vehicle, be sent to control center by means of same with other observed readings that the measurement mechanism that guideway vehicle has nothing to do detects and include in assessment.On the other hand, also can assess other observed readings individually in method step before and consider the only result of described assessment by means of during the algorithm evaluation observed reading preset in the heart in the controlling.Such as, detect about for describing weather other observed readings multiple as the measurand of temperature, pressure or humidity.To derive thus aeromancy.Therefore, the assessment of other observed readings can obtain the prediction of the temperature value considered when assessing the observed reading of guideway vehicle.Therefore, carry out by means of observed reading other observed readings that directly or indirectly basis and orbit measurement independently detect of the algorithm evaluation guideway vehicle preset in the heart in the controlling.
In order to assess, many different algorithms can be applied.Like this, according to one embodiment of present invention, the algorithm preset can be suitable for carrying out trend analysis to the measurement sequence of the observed reading of the measurand preset.If temperature changes along with the time, so can predict thus: probably when exceed default boundary temperature.Other algorithms are included in the list of the exhaustive of following opening: the other standards model of frequency analysis and statistical analysis.
According to another improvement project of method according to the present invention, at least one guideway vehicle comprises the vehicle part of at least one group of same configuration, wherein
-detect at least one observed reading of measurand preset about the vehicle part of each same configuration by means of at least one measurement mechanism of guideway vehicle,
-detected observed reading is transferred to the control center being arranged on line side from guideway vehicle,
-in the controlling in the heart by means of the observed reading that the algorithm evaluation preset detects, and
-provide at least one result of assessment for being exported by control center.
As the simple assessment by means of the algorithm preset, the observed reading of the vehicle part of same configuration is compared in the heart in the controlling mutually.Subsequently, when the numerical value that other observed reading deviations of the observed reading of vehicle part and the vehicle part of other same configuration are at least preset, the state in bad order of the vehicle part of same configuration can be inferred.
Especially, detect the observed reading be compared with each other about identical vehicle part simultaneously.
According to another improvement project, the output signal when the first numerical value that other observed reading deviations of the observed reading of vehicle part and the vehicle part of other same configuration are at least preset.Described signal such as can have the form of acoustic alert or vision display.Another signal is such as created on the contract period within the default time limit in the maintenance schedule of guideway vehicle.
In order to compare the observed reading of the vehicle part of same configuration, can such as perform following method step in the heart in the controlling:
– stores the observed reading being transferred to control center from guideway vehicle;
– computation and measurement value spacing to each other;
– by spacing with preset the first numeric ratio comparatively.
When the spacing of the observed reading of the observed reading of the first vehicle part and the vehicle part of other same configuration exceedes the first default numerical value, infer the state in bad order of the first vehicle part.
Except each observed reading spacing be to each other detected while the vehicle part simply determining same configuration, other algorithms many also can consider the deviation identifying at least one observed reading and other observed readings.Algorithm known for this is such as determine each residual error about the pattern function obtained by method of least square, determines and each deviation of expectation value and other Statistic analysis models.
In addition, multiple numerical value can be preset, to obtain different conclusions when deviation and to export corresponding result if desired.Therefore, it is possible to only show maintenance to be carried out during the first numerical value at least one observed reading deviation, and corresponding vehicle part can be shown during second value in deviation close to fault and warn with signal before this.
According to another improvement project, the at least the first numerical value is preset according to other observed readings about measurand and/or other measurands one or more, other observed readings described detect by means of measurement mechanism, and described measurement mechanism and guideway vehicle have nothing to do and and then also have nothing to do with the running state of guideway vehicle.So, naturally also independently detect other observed readings with the running state of the vehicle part of same configuration.
Other measurands are such as speed, rotating speed, electric current, voltage, temperature, pressure and/or acceleration/accel, can detect observed reading by guideway vehicle about other measurands and/or independently detect observed reading with guideway vehicle.Corresponding measurement mechanism can be arranged similarly.Rotating speed and/or temperature such as can by electrical motor, driving device or wheel detection.
The observed reading of at least one measurand preset is such as by traction motor and/or the change-speed box detection of guideway vehicle.In one embodiment, guideway vehicle has traction motor and/or the change-speed box of at least two same configuration, and it has the corresponding measurement mechanism for recording observed reading.In one embodiment, guideway vehicle respectively has two temperature-sensitive stickers for each traction motor and/or each change-speed box.In addition, guideway vehicle at least one can have the temperature-sensitive sticker of the ambient temperature for detecting orbit measurement, and described temperature-sensitive sticker is such as arranged on the covering of guideway vehicle.
According to a specification sheets example, the spacing between each observed reading of the measurand of the running state about sign guideway vehicle of the vehicle part of calculating same configuration.If measurand is temperature and traction motor about the same configuration at the similar position be positioned at respectively on guideway vehicle detects corresponding observed reading, the first numerical value so preset and the ambient temperature of guideway vehicle have nothing to do, because all observed readings when ambient temperature raises about the traction motor of same configuration move up equally.But if the vehicle part of same configuration is arranged on very different positions in guideway vehicle or on guideway vehicle, so ambient temperature can have impact to the observed reading of the temperature of each vehicle part.When remote monitor and control fleet, also consideration ambient temperature can be designed.Like this, when the ambient temperature around the first guideway vehicle is obviously higher the observed reading of the temperature of the traction motor of the first guideway vehicle raise to raise with the observed reading of the temperature at the traction motor around the second guideway vehicle in the significantly lower situation of ambient temperature of the second guideway vehicle compared with obvious.Additionally, the observed reading about other measurands can also be considered.Like this, from arrange in the soleplate but the vehicle part of same configuration is different in other respects, the temperature being such as arranged on the vehicle part on the top of guideway vehicle is substantially relevant with solar irradiation.For each observed reading of the measurand preset of the vehicle part about same configuration, according to the observed reading about other measurands one or more and/or default first numerical value can be carried out according to the observed reading about the identical measurand independently detected with the vehicle part of same configuration.Thus, the first numerical value can be different and/or strange land is different from each other because of corresponding vehicle part because of the observed reading of the measurand preset of the vehicle part about same configuration.
Now, if the traction motor of same configuration has two temperature-sensitive stickers respectively, first temperature-sensitive sticker at the first position of each traction motor, at second position different from the first position of each traction motor, so can only carry out being compared to each other and the observed reading of the second temperature-sensitive sticker be compared to each other similarly by the second other temperature-sensitive sticker by the observed reading of the first temperature-sensitive sticker.But this and not necessarily are required.In the same manner, about the measurand preset all observed readings and as being compared to each other about other observed readings that are identical and/or different measuring variable as described in above, to infer the state in bad order of vehicle part, such as its mode is: the observed reading about other measurands compared, to derive the first default numerical value thus with the observed reading about the measurand preset.
As already described, not only detect simultaneously about identical vehicle part by the observed reading be compared to each other, and can to detect about the observed reading of other measurands one or more and/or the observed reading about identical measurand that independently detects with identical vehicle part simultaneously.This does not get rid of: the outlier of the measurement sequence that filtering is made up of the observed reading of following successively, or level and smooth described measurement sequence.
Can the whole fleet of remote monitor and control by means of method according to the present invention.Such as, the mode of the vehicle part of at least one group same configuration is comprised by the fleet of guideway vehicle, wherein detect the observed reading of at least one measurand preset about the vehicle part for each same configuration, wherein observed reading is transferred to the control center arranging line side from guideway vehicle, wherein in the heart the observed reading of the vehicle part of same configuration to be compared in the controlling and wherein when the numerical value preset of other observed reading deviations of the observed reading of a vehicle part and the vehicle part of other same configuration, so infer the state in bad order of the vehicle part of same configuration.Similarly, in multiple guideway vehicles of vehicle part with same configuration, when the state in bad order of in the vehicle part of inferring same configuration, also can output signal.So this can export just on the guideway vehicle comprising the vehicle part of inferring its state in bad order.Except the vehicle part about all guideway vehicle same configuration, especially structure is identical too for the guideway vehicle of fleet.
Assessed the observed reading of multiple guideway vehicle by middle ground, the service sequence of guideway vehicle can be determined very simply.
In order to perform according to method of the present invention, the guideway vehicle of guideway vehicle especially passenger traffic comprises at least one thus for detecting the measurement mechanism of the observed reading of at least one measurand and at least one is for being transferred to the transmitter of control center from guideway vehicle by observed reading.Survey record device is considered as the equivalents of measurement mechanism.
And for performing at least one controller of algorithm evaluation observed reading comprising at least one receptor for observed reading is transferred to control center from guideway vehicle according to the control center of method of the present invention and be used for by means of presetting.Controller is suitable for by algorithm evaluation observed reading different from each other with improved procedure.Algorithm such as exists as software.Described algorithm can be easily replaced and/or can be changed.In addition, controller is applicable to processing other observed readings detected by means of the measurement mechanism that other and guideway vehicle have nothing to do.
Be configured for performing the system according to method of the present invention and equipment by the guideway vehicle of type described at least one and the control center of type described at least one.In addition, it can comprise at least one memory device, and algorithm stores on a memory, and described controller can access described memory device.In addition, it can have at least one mechanism, such as input equipment, especially so-called man machine interface, to change default algorithm.Therefore, controller is suitable for by means of algorithm evaluation observed reading different from each other.Additionally or alternatively, controller is suitable for and relative configurations is observed reading for assessment of guideway vehicle and other observed readings independently detected with guideway vehicle in an advantageous manner.
If at least one guideway vehicle has the vehicle part of at least one group of same configuration as in above-mentioned example, such as two or more traction motor, wherein guideway vehicle comprises at least one respectively for detecting the measurement mechanism of the observed reading of at least one measurand preset about the vehicle part for each same configuration, such as each traction motor has at least one for recording the temperature-sensitive sticker of the observed reading of the temperature about measurand and traction motor, then control center has the controller that at least one is suitable for comparison measurement value.Certainly, identical content is also applicable to have multiple system with the guideway vehicle of the vehicle part of same configuration.
